Abstract
Provided are a meta data encoding/decoding method and apparatus. The meta data decoding method includes decoding a media signal containing a media object, and decoding meta data corresponding to the media object. During the decoding of the meta data signal, decoding of the meta data is skipped when the meta data that is to be decoded is identical to already decoded meta data.
